"Sit down and don't move" is the most basic way to express the formation of ownership of dog.  And this command is also the most effective order when you go outside with your dog.   Choose a quiet interior place to train 15 minutes each time.  Do not expect the dog will soon be subject to this Order.

Step 1: show your dog its favorite snacks with your right hand.  When the dog looks at food, order it to "sit down."

Step 2: maintain traction with an appropriate tension, step forward your right foot and order the dog "don't move."

Step 3: praise the dog and then slowly walk around it. Don't loosen traction belt, then you're unnecessary to repeat the command.

Step 4: After a few training class, the dog has learned to follow the belt to sit down. Now release the traction belt, and repeat the above steps. When the dog can perform well, give it an appropriate praise.

Step 5: If the dog begins to move, you can seize the collar with your left hand and hold down its back to order it to sit down with your right hand.
